Technical Field

[0001] This utility model relates to the technical field of batching and weighing systems, and in particular to a dustproof optimization of a feeding system for a formula machine. Background Technology

[0002] The small-material batching and weighing system is an intelligent production equipment developed for scenarios involving the batching of multiple varieties and trace amounts of materials. It primarily serves the high-precision batching needs of industries such as rubber products, plastic modification, friction materials, and powder metallurgy. This system achieves coordinated operation of dynamic weighing and process control through a high-precision screw feeder mechanism combined with intelligent variable frequency speed regulation technology. It also constructs a comprehensive control system covering the entire process from material conveying and weighing to data management, which has significant application value in improving the automation level and quality control capabilities of small and medium-sized enterprises.

[0003] Current multi-hopper batching systems have the following technical drawbacks: The system employs a discrete hopper layout, with each hopper discharging material by gravity into a central collecting cylinder through its bottom outlet. Because the material to be processed is a fine powder, dust dispersion occurs during the free-fall process due to airflow, leading to the following technical problems:

[0004] 1. Scattered dust often contains toxic components, and long-term exposure to dusty environments can pose health risks to workers.

[0005] 2. Suspended dust causes dust to accumulate on the surface of the equipment, which can easily damage the equipment and make equipment maintenance complicated. Utility Model Content

[0006] Therefore, in view of the above problems, this utility model proposes a dustproof device for the feeding system of a formula machine to prevent dust from escaping.

[0036] refer to Figures 1 to 5 The present utility model embodiment discloses that:

[0037] A dustproof device for a feeding system of a formula mixing machine includes a dustproof box 1. A material cylinder placement port 2 is provided on one side of the dustproof box 1 to facilitate the horizontal insertion or removal of material cylinders. A door 3 is hinged to the material cylinder placement port 2 via a pivot. During the mixing operation, the dustproof box 1 is kept closed by the door 3, only briefly opened when changing material cylinders to reduce dust escape from the material cylinder placement port 2. Several flexible connecting pipes 4 are provided on the top of the dustproof box 1. These flexible connecting pipes 4 are used to connect to the discharge pipe of the formula mixing machine. The flexible connecting pipes 4 are connected to the interior of the dustproof box 1 to form a discharge port. The ingredients enter the material cylinder inside the dustproof box 1 through the flexible connecting pipes 4, facilitating connection and adapting to positional deviations in the discharge pipes of different formula mixing machines, ensuring a sealed feeding path. The dustproof box 1 is equipped with a weighing device 10 (such as a load cell) fixed inside by bolts. The material cylinder is placed on the weighing device 10 inside the dustproof box 1. During the feeding process, the weighing device 10 monitors the weight of the material cylinder in real time. When the preset value is reached, the feeding is automatically or manually stopped to achieve accurate feeding. A dust removal hose 5 is provided on one side of the dustproof box 1 and is connected to the inside of the dustproof box 1. The free end of the dust removal hose 5 is configured to connect to a dust collector. After the material is fed, the dust collector continuously draws the dust-laden air in the dustproof box 1 through the dust removal hose 5 to form a negative pressure environment and prevent dust from escaping. Through the above settings, dust is effectively prevented from escaping into the working environment, thereby significantly improving the working environment and avoiding the impact of dust on mechanical equipment.

[0038] The dustproof box 1 is equipped with a vibration excitation component. In this embodiment, the vibration excitation component is specifically a vibration motor 6 located on the rear side of the dustproof box 1. The vibration generated by the vibration excitation component is transmitted to the flexible connecting pipe 4 to shake off the ingredients attached to the inner wall of the flexible connecting pipe 4, thereby reducing the risk of blockage caused by ingredient residue and avoiding mixing of different batches of ingredients due to pipe wall residue, thus ensuring the purity of the formula.

[0039] The bottom of the dustproof box 1 is provided with a spring damping mechanism 7. The spring damping mechanism 7 is configured to respond to the vibration of the dustproof box 1 and form vibration attenuation in the vertical direction. Specifically, the bottom of the dustproof box 1 is provided with feet, and a spring is provided between the feet and the dustproof box 1. The vibration motor 6 drives the dustproof box 1 to vibrate by adapting the spring deformation, thereby reducing the vibration transmission to external equipment and reducing the risk of mechanical fatigue.

[0040] The dustproof box 1 is equipped with a material cylinder limiting mechanism, which is used to keep the material cylinder aligned with the discharge port. Specifically, the material cylinder limiting mechanism includes limiting plates 8 symmetrically arranged on both sides of the inner wall of the dustproof box 1, and elastic connectors 9 connecting the limiting plates 8 and the inner wall of the dustproof box 1. When the material cylinder is placed horizontally from the material cylinder placement port 2, the limiting plates 8 can be clamped by the elastic connectors 9, thereby aligning the material cylinder with the discharge port to reduce spillage of ingredients during the feeding process.

[0041] The limiting plate 8 has an arc-shaped abutment surface 801 on the side away from the elastic connector 9. An arc-shaped limiting groove 802 is located at the center of the side of the limiting plate 8 with the arc-shaped abutment surface 801, and the arc-shaped limiting groove 802 is adapted to the side wall of the material cylinder. In the initial state, the minimum distance between the arc-shaped abutment surfaces 801 on both sides of the elastic connector 9 is less than the outer diameter of the material cylinder. During the placement of the material cylinder, specifically when the material cylinder is pushed laterally into the material cylinder placement port 2, its side wall first contacts the arc-shaped abutment surface 801 of the limiting plate 8. The arc-shaped abutment surface 801 guides the material cylinder to slide towards the center position, initially correcting the material cylinder's posture. As the material cylinder continues to penetrate deeper, its side wall embeds into the arc-shaped limiting groove 802, and the curvature of the arc-shaped limiting groove 802 fits against the outer wall of the material cylinder, thereby achieving precise alignment.

[0042] The installation height of the limiting plate 8 is higher than the working plane of the weighing device 10, so as to avoid collision with the weighing device 10 when the material cylinder is placed, thereby protecting the weighing device 10 and preventing it from being damaged.

[0043] Each of the limiting plates 8 is provided with a guide rod 11, the other end of which protrudes from the dustproof box 1. The elastic connector 9 is a compression spring sleeved on the guide rod 11. The guide rod 11 protrudes from the dustproof box 1, forming an internal and external linkage structure. When the material cylinder is placed in, the operator can intuitively judge the opening and closing state of the limiting plate 8 by the movement of the exposed part of the guide tube, which helps to quickly align the position of the material cylinder and reduce the difficulty of operation. At the same time, the compression spring is sleeved on the guide rod 11, and its two ends abut against the inner wall of the dustproof box 1 and the limiting plate 8, respectively, to rigidly constrain the extension and contraction path of the compression spring, prevent the compression spring from deflecting when compressed, and ensure that the limiting plate 8 always moves in the preset direction, thereby improving the clamping stability.

[0044] In another embodiment, a plurality of feed pipes 12 are provided on the upper side of the dustproof box 1, and the flexible connecting pipe 4 is fixed to the feed pipe 12 by clamps (not shown in the figure). The lower side of the feed pipe 12 passes into the dustproof box 1, and the discharge port at the lower end of the feed pipe 12 is the aforementioned discharge port. It is worth mentioning that an air outlet pipe 13 is provided on one side of the dustproof box 1. The air outlet pipe 13 is connected to the inside of the dustproof box 1, and the dust removal hose 5 is fixed to the air outlet pipe 13 by clamps. The clamp structure facilitates pipe replacement or cleaning and reduces maintenance costs.

[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent substitutions for some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
